Old Galaxy Finds Fountain of Youth


In a galaxy far, far away, a theft of cosmic proportions is taking place in an effort to claim the fountain of youth. 


A massive galaxy is stealing a billion suns worth of gas from a smaller galactic neighbor. In space, gas is a hot commodity. Really hot. In this case, about 1,340 degrees Fahrenheit (730 degrees Celsius). And it's great for making new stars.  


The robber, called 3C 326 North, is about the mass of our Milky Way galaxy, and its victim, 3C 326 South, is about half its mass. They are close enough to perturb each other gravitationally and might eventually collide.


Such galaxy mergers are common in the universe: Gas and stars in two nearby galaxies become tangled until they become one larger galaxy. The case of 3C 326 is the clearest example yet of large quantities of gas being heated and siphoned from one galaxy to another.


This could be an important phase in galaxy mergers that we are just now witnessing. The same thing will happen to our galaxy (Milky Way) when she collides with Andromeda galaxy in the far future. Since andromeda is bigger than Milky Way we’re gonna be the victim.


The scene of the crime is about a billion light-years away. So in reality, the theft took place a billion years ago, but the light revealing it has only just arrived.
